MSNBC hosts Ali Velshi and Stephanie Ruhle on Thursday schooled Brad Thomas, a member of the Donald Trump for President advisory board and author of The Trump Factor, after he tried to lecture them on the economy under Trump.

Velshi and Ruhle asked Thomas about reports that Gary Cohn, chief economic advisor to Trump, is “disgusted” and “upset” over the president’s Charlottesville remarks and is considering leaving the administration. Those rumors, Velshi and Ruhle pointed out, are causing the stock market to drop.

“Business leaders across industries have said, ‘Mercy, we’re out,’ so where’s the selling point for President Trump now?” Ruhle asked.

Thomas replied that the economy is “doing very very well,” and he looks at the economy “long term.”

“The number one catalyst that nobody is going to talk about—especially your show, and others like this—is the number one catalyst is the corporate tax,” Thomas said. “This is the market mover.”

“You’re talking to two financial journalists,” Velshi replied, informing Thomas that the market “started going up on March 9, 2009.”

“There is nothing Donald Trump has done to cause the market to be where it is,” Velshi said.

“That’s not true, Ali and I talk about it all of the time,” Ruhle replied.

“You should fire your press person,” Velshi added. “If they didn’t tell you were coming on TV with Velshi and Ruhle … this is a silly conversation to have with us. You should go to other people’s media and say these things but not to us, we cover this every day in and out. And the fact is those CEO’s got pressure sure from their shareholders, boards and customers who say, ‘We can’t stand next to this president who is embracing neo-Nazis.’ How is that good for business?”

“As I said earlier, I think the most significant piece of this is job creation,” Thomas replied. “I’m going to stay on that.”

Ruhle later invited Thomas back on in six and a half weeks to discuss White House’s promise of a tax reform bill, a pipe dream according to sources within the administration.

“Can you watch some of our show so you don’t come here and say the mainstream media doesn’t cover this stuff?” Velshi asked. “Because we really, really do I’ll send you some links.”
